The UE-48LI3750I ESS Unit is a lithium iron phosphate battery energy storage system designed to provide energy storage for photovoltaic power generation users through parallel combination. It can store excess electricity from a photovoltaic power generation system during the day and supply stable power to user equipment as a power backup at night or when needed. This system aims to improve the efficiency of photovoltaic power generation and increase electric power efficiency through peak load shifting.
The UE-48LI3750I functions as a standard battery system unit. Users can connect multiple UE-48LI3750I units in parallel to form a larger capacity battery pack, meeting long-term power supply needs. It is particularly suitable for energy storage applications characterized by high operating temperatures, limited installation space, long power backup times, and extended service life. The system's positive electrode materials are lithium iron phosphate (LiFePO4), which contributes to its safety and longer lifespan. A Battery Management System (BMS) effectively manages the battery cells, providing protection functions such as over-discharge, over-charge, over-current, and abnormal temperature. The unit features self-management for charging and discharging, including single-core balancing. Its intelligent design incorporates an integrated inspection module. Flexible configurations allow for parallel connection of multiple batteries to achieve longer standby times. The system operates with self-ventilation, resulting in lower system noise. It exhibits less battery self-discharge, allowing for a recharging period of up to 10 months during storage. The battery has no memory effect, enabling shallow charging and discharging.
The device is designed for indoor installation, avoiding direct sun, wind, conductive dust, and corrosive gas. The installation location should be away from the sea to prevent brine and high humidity. The ground for product arrangement must be flat and level, with no flammable or explosive materials nearby. The optimal ambient temperature for operation is 15°C to 30°C. The front panel includes a Power switch (OFF/ON) which must be in the "ON" state during use. A Ground connection point ensures proper grounding. Positive and Negative sockets are for battery output connections. A SW (battery wake/sleep switch) allows users to power on or off the battery by pressing and holding for 3 seconds when the OFF/ON switch is in the ON state. SOC (State of Charge) indicators, represented by green lights, show the remaining battery power. An ALM (Alarm) indicator flashes red for alarms and stays solid red during protection status. A RUN indicator flashes green during standby and charging, and stays solid green during discharging. CAN/485 ports are for communication cascade, supporting CAN/RS485 communication (factory default is CAN). A DRY CONTACT port is also available. An ADD DIP switch is used for configuration, particularly when batteries are connected in parallel.
The DIP switches define communication protocols and baud rates.
